Programming Mode: Note: The Program Code is located on the erial Plate on this unit after the word Code. 1. pen the Fresh Food door and hold the Fresh Food door light switch closed while pushing the Temperature Down Key pad 3 times consecutively. Note: The 3 Keystrokes must be done consecutively and within 10 seconds. 2. Release the Fresh Food door light switch. 3. The control will display PE to confirm entry into the programming mode. P. Entry is confirmed by pressing the Down key once more. Note: All control functions will be turned off (Compressor, Defrost, Evaporator Fan, the damper will remain in its current position).. The control will display the current Program Code. This value should be validated with the Program Code printed on the unit serial plate. 2 February 2006 3 1602696 E Note: If the Program Code is correct, the Programming Mode is exited by closing the door(s). 6. To set the desired Program Code number press the and UP keys. The corresponding digit will be advanced with each key press. 7. nce the desired Program Code is displayed, press the Down Key until the Program Code begins flashing indicating it has been saved. Note: If you attempt to enter an invalid Program Code the control will not save the new code, but will flash the old code and this will be displayed. (The unit will NT run with a Program Code of 00). 8. nce the Program Code has been saved the Programming Mode is exited by closing the door(s). If the new code is incorrect this process should be repeated after closing the door(s). The Programming mode can be exited at any time by closing the Door(s). Defrost peration: The Control Board adapts the compressor run time between defrosts to achieve optimum defrost intervals by monitoring the length of time the defrost heater is on. After initial power up, defrost interval is hours compressor run time. Defrost occurs immediately after the hours. Note: nce unit is ready to defrost there is a minute wait time prior to the beginning of the defrost cycle. ptimum defrost is 1 minutes. Each additional minute the defrost thermostat remains closed, 1 hr. is subtracted from the previous defrost interval. Each minute the thermostat opens prior to optimum defrost, it extends the next defrost interval 1 hr. When defrost thermostat opens there is a -6 minute drip time before compressor restarts or Control Board will terminate defrost at 2 minutes if defrost thermostat has not opened and will reset the defrost interval to the 8 hr. minimum setting. hours of continuous compressor run resets the next defrost interval to 8 hours and will initiate a defrost, if 8 hours of compressor run time has also occurred. Forced Defrost Mode: The forced defrost function is performed using the refrigerator display and keypad. Enter the Forced Defrost Mode by performing the following sequence of events: 1. Hold the refrigerator door light switch closed. 2. Press the Temperature Down keypad 3 times consecutively. Note: The 3 keystrokes must be consecutive and within 10 seconds.
3. Release the refrigerator door light switch.. The control will display Fd to confirm entry into the Forced Defrost Mode. F. Entry is confirmed by pressing the Down key once more. The unit is off and in the Defrost Mode. Note: All control functions will be turned off (Compressor, Defrost, Evaporator Fan, the damper will remain in its current position). 6. The control will default to the short run period test as shown here.. 1602696 February 2006 Note: You can toggle between the ()hort and (L)ong test mode by pressing the UP Long Test mode is used for factory test and should not be used in the field. 7. nce the desired mode is displayed, confirm the forced defrost by pressing the down Key once. The defrost will begin immediately and the display will return to a normal operating display with set point values. 8. Close the door(s). You are in the defrost mode. Note: Forced Defrost mode can be exited at any time prior to step 7 by closing the Door(s). ervice Test Mode: The service test functions are performed using the refrigerator display and keypad. Enter the ervice Test Mode by performing the following sequence of events: 1. Hold the refrigerator door light switch closed. L 2. Press the Temperature Up keypad 3 times consecutively. Note: The 3 Keystrokes must be done consecutively and within 10 seconds. 3. Release the refrigerator door light switch.. The control will display E to confirm entry into the service mode.. Entry to the ervice Menu is confirmed by pressing the Up key once more. 6. The control will display its software version for 3 seconds. 2 E 7. Following the software revision display the freezer display will read the first test number in the diagnostic tree. The refrigerator display will be blank. 1 Note: All control functions will be turned off (Compressor, Defrost, Evaporator Fan, the damper will remain in its current position). 8. You are now in the ERVICE TET operational mode and may use the diagnostic tests. The ervice Test Mode can be exited at any time by closing the Door(s). Key.
